    Having a lot of fun with it but finding myself a issue wich i can't figure how to fix it.


    The issue i have is, the subtitles are been grabbed by leds and producing light wich isn't suppose to happen

    I've been palying around with some settings like blackbar detection or by lowering the Horizontal Led Depth value but non make sense and i'm out of ideas.

    Hi


    I use hyperhdr and using a wemos d1 to control the leds.


    While i was reading awa his GitHub and came across hyper serial esp8266 / hyper serial WLED.


    How do you connect this to the pi?

    I believe just by a usb cable wich will power the wemos by the pi...


    When I do this my leds not responding.


    Any help in this would be nice.

    So when I play a movie/serie on my xbox one x with netflix, as soon as I start netflix... Hyperion isn't capturing any video and thus so it states as no signal...
    It only happens when playing netflix....
    I would think this has something to matter with hdcp2.2?
    It also happens only when I set the xbox on 4k using 1080p everything is just fine.


    Anyone know this problem and how to solve?


    Something like this?


    before
    {
    "index" : 0,
    "hscan" : { "minimum" : 0.3846, "maximum" : 0.4103 },
    "vscan" : { "minimum" : 0.9200, "maximum" : 1.0000 }
    },
    {
    "index" : 1,
    "hscan" : { "minimum" : 0.3846, "maximum" : 0.4103 },
    "vscan" : { "minimum" : 0.9200, "maximum" : 1.0000 }
    },
    {
    "index" : 2,
    "hscan" : { "minimum" : 0.3846, "maximum" : 0.4103 },
    "vscan" : { "minimum" : 0.9200, "maximum" : 1.0000 }
    },
    {
    "index" : 3,
    "hscan" : { "minimum" : 0.3846, "maximum" : 0.4103 },
    "vscan" : { "minimum" : 0.9200, "maximum" : 1.0000 }


    after


    {
    "index" : 0,
    "hscan" : { "minimum" : 0.3846, "maximum" : 0.4103 },
    "vscan" : { "minimum" : 0.9200, "maximum" : 1.0000 }
    },
    {
    "index" : 1,
    "hscan" : { "minimum" : 0.3846, "maximum" : 0.4103 },
    "vscan" : { "minimum" : 0.9200, "maximum" : 1.0000 }
    },
    {
    "index" : 2,
    "hscan" : { "minimum" : 0.3846, "maximum" : 0.4103 },
    "vscan" : { "minimum" : 0.9200, "maximum" : 1.0000 }
    },
    {
    "index" : 3,
    "hscan" : { "minimum" : 0.3846, "maximum" : 0.4103 },
    "vscan" : { "minimum" : 0.9200, "maximum" : 1.0000 }

    ok which grabber do you have?


    ut0007 when i connect the hdmi to av to av tv the source is good!


    or could be a resistor on the data output line be a pottential issue? the same as on the data input


    ______________________________________________


    So i disabled the black border detection and it when little less flickering... but still



    So been playing some little bit and after changing this in the code it now only flickers once a seconds but i don't think this is right... it's on 1hz but flickers every 1 sec, so whats going on here??


    Code
    // FRAME GRABBER CONFIG
        "framegrabber" :
        {
            "width" : 64,
            "height" : 64,
            "frequency_Hz" : 1.0,
            "priority" : 900
        },



    My level shifter is connected exectly like this, is this correct?


    Edit again...


    When i disable this peace of code the flickering stops...


    Code
    // FRAME GRABBER CONFIG
    //    "framegrabber" :
    //    {
    //        "width" : 64,
    //        "height" : 64,
    //        "frequency_Hz" : 20.0,
    //        "priority" : 890
    //    },



    SO I FINALLY GOT IT WORKING NOW!!!
    but one question.. i think by my opinion that there are to much leds in comparison with the colors the produce from the screen...
    So how can i setup so that 2 leds have the same surface to pick the same colours so the smoothing is better...


    I got this with this code



    and got this video


    https://drive.google.com/open?…FHzbcAe0FIAzxaI99PTeXuAyC


    I lowered the value to 20,000 , the flickering is less but it's stil noticeble,

    which leds? config please



    I got WS2801 leds 5v+, Data input, Data Output and GND


    here is my config but that is oke for sure
    I think i need a level shifter.. i got one now i connect Data line from the leds to the level shifter but does the Data output wire also need on the level shifter?or only the data line?




    Well as i don't want to steal some one else their topic i start one here.


    Finally after 2 months i got everthing working now, leds respond frame grabber grabs the frame, but i got only one problem and thats flickering leds..


    How i connected everything by power


    20A 5v psu i connected a + - line to the leds and one to the pi both have a transistor on it 1000uF both on the same + and - of the PSU.
    So i got a central point where my pi and leds ( - ) come together from there it goes to the PSU
    Then i got another ground from the psu to the pi and a separet + .


    Does this flickering happen because the pi gpio is 3,3V and the leds DATA 5v?
    already ordered a level shifter so have to wait for that

    Ah.. you didn't specify your LED type. You may need the resistor or even a level shifter.


    I use ws2801 leds


    I need 470ohm on Data input but do i need also one on clock output?


    Or better question wicht resistor or transistor do this setup need on wich lines?
    Found different setups on the internet... so it's a bit confusing.
